I seldom show off my system anymore, but when I do:
My own recordings of my wife's rock drum kit.
Malcolm Frager Plays Chopin, Telarc (IMHO, the best piano recording ever made, and I'm a huge fan of solo piano. Frager had incomparable talent.)
The Harper Brothers, Remembrance, Live at the Village Vanguard, Verve (Engineered by David Baker, one of the best who ever practiced the craft. Surprisingly good original classic jazz.)
Peter Erskine New Trio, Joy Luck, Fuzzy Music (Other than my wife, Erskine is my favorite drummer, and this is a true purist recording. This album can sound very close to live on the right system. I almost spent a lot of money after hearing it on Sound Lab electrostatics.)
Herb Alpert, Colors, ALMO (Skillful contemporary jazz, very well recorded.)
Yellowjackets, Blue Hats, Warner Brothers (Track 2 will really exercise a subwoofer. IMO, the best Yellowjackets album.)
Rossini Overtures, Orpheus Chamber Orchestra, DG (Just plain fun, well-recorded by a great orchestra that functions without a conductor.)
William Tell & Other Favorite Overtures, Cincinnati Pops, Telarc (IMHO, the best overtures recording ever made. The William Tell Overture is simply awesome on this CD.)
